Does overnight duty affect vascular endothelial function?

Table 4 A multiple linear regression analysis for RHI

Variables	Beta	SE	Standard beta	p value	VIF
Model 1
SBP (mmHg)	− 0.01	0.01	− 0.21	0.071	1.04
VAS scale (%)	− 0.01	0.00	− 0.25	0.034	1.04
Model 2

Table shows the participants were divided into 2 groups by RHI: normal (< 1.67), and abnormal (≥ 1.67) groups
HR, heart rate; RHI, Reactive hyperemia index; rMSSD, root mean squared standard deviation; SBP, systolic blood pressure; SDNN, standard deviation of normal-to-normal intervals; SE, standard error; VAS, visual analog scale; VIF, variance inflation factor
Statistical analysis was done with multiple linear regression analysis where p < 0.05 was considered as significant
